ALLNET 4duino senzor pulza in srčnega utripa (ALL-KS_Heartbeat)

The ALLNET 4duino Pulse and Heart Rate Sensor (ALL-KS_Heartbeat) is an optical pulse sensor module designed for DIY electronics projects. It uses photoplethysmography (PPG) to detect heart rate through fingertip or skin contact, outputting an analog voltage signal proportional to pulse activity. Compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers, this sensor is ideal for educational kits, prototyping, and health monitoring experiments.

Advantages

Easy to integrate with standard 3-pin headers (VCC, GND, Signal) and operates on 3.3V to 5V DC. The built-in LED provides visual pulse indication, and mounting holes allow secure attachment. Low current consumption (<10 mA) makes it suitable for battery-powered projects.

Suitable for

• DIY heart rate monitors
• Educational STEM kits
• Microcontroller prototyping
• Biometric sensor experiments
